These days, mountain bike bars are available in widths ranging from less than mm all the handoebars up to mm or more. Cross-country riders will usually prefer narrower bars compared to trail and downhill riders.
Also keep comfort in mind. If you have short arms, you may not want the widest bars available, even if you are a super aggressive gravity rider. Aluminum mh are generally the least expensive but are also the heaviest.
Titanium bars can be more expensive than carbon, and are generally heavier too. Carbon bars also have a much more finite lifespan than aluminum or titanium bars from repeated flexing. Many of these choices are based on extreme use cases like bikepacking and ultra-endurance riding where riders need to utilize multiple hand positions throughout the ride to avoid fatigue.
If your stem was already at the top of the stack, and you need to go higher you have some options. Measured in degrees, the rise of a handoebars is the difference in height between the steerer clamp and the bar clamp. Positive rise is when the stem is flipped to raise the bar clamp height above the steerer clamp.
Negative rise is useful for racers looking to gain a low, aero position. Riders of bike with very tall head tubes also sometimes use negative rise to attain the same positon as a bike with a shorter head tube length.
Similarly some 29er MTB riders, especially XC racers, will use negative rise stems to attain a low racing position. The combination of stem and spacers —in whatever order you need — should result in the stack being greater than the height of the steerer tube by 3mm.
This allows the top cap bolt to be done up and pull the steerer and top cap together — preloading the headset bearing. Rise measurements are given in millimetres, in the basic metrics of each bar.
In this case you will need a new fork. Be sure to ask your local Evans Cycles team for advice on the best replacement fork for your bike and style of riding.

Most mountain and hybrid bikes use the Some modern mountain and road bikes use a Instead of a new stem, you can also purchase a quill stem extender. This is basically a tube of metal that inserts into your steerer tube, and then your original stem inserts into the top of the extender.
Threadless stems are found on most modern mountain and road bikes, and some mid-level and higher-end hybrid bikes. The term "threadless" technically refers to the absense of threading on the steerer tube and headset, and thus the absense of the two large nuts on the headset.
A threadless stem clamps onto the outside of the steerer tube, and is hoow in place by one or two bolts situated horizontally at the back end of the stem. You can adjust the height of the stem by swapping spacers from above to below, and vice-versa.
If there are no spacers above the stem, then there is no way to move the stem any higher. You have a couple of options for fo your stem and handlebars in this situation.
First, you can install a steerer tube extender. This clamps to the top of your steerer tube, and then your stem clamps to the top of the extender. This can give you 2 to 4 inches of additional height.
You can also choose to purchase a replacement stem with a different length and d that gets you into your desired riding position.
